I've only had my PNP for a few weeks now and the only things I'd suggest;
- Check/tighten all motor mounting screws
- Replace the stock prop with a apc 12x6e (or 13x4e for a little slower flying speed) and make sure you properly balance these
- Use the fully threaded bolts for the wings and the shouldered ones on the elevator
- if your strip is a little lumpy/bumpy ditch the wheel pants and use larger 3 inch light weight wheels. You will need a couple of extra wheel collars to hold the whells on. I drilled out a couple of 3mm ones I had with a 9/64 inch drill bit.

These are the main things I've found out. So far I really love this plane and I'm sure you will too.

Ok, I just looked at the Length of both the SK35-48 and the 3648 (without the tip of the shaft) and they are both 51mm. Now if the Data on HK's website is correct (lots of times it may not be) then that means the shaft for the SK motor is identical and will fit perfectly in the 3648 (the C-clip will align perfectly with the end of the motor and hold it securely in place).

I have broken my fuse no less than 4 times. I have broken both elev tips. I have ripped off the rudder. I have ripped of the ailerons and recently about 4 inches of the wing tip including snapping the aileron hinge rod, I have broken many props, bent one shaft and bent the LG many times, like every single time I fly, but it all glues back together. It gets heavier over time.

Until I get to where I feel very comfortable, I do not plan on replacing any foam parts or if I can no longer repair it. It is not pretty, but the uglier it gets, the more I relax.....

The fuse is not available yet in US, that I have found. Most other parts are and may be showing up in hobby shops.

I say, glue it together the best you can.....

Good luck

mmm yes .. glue and.. well missing part of wing and rudder is gone.. lost in the woods..

yanked all servos out.. the servo arm moves ezly on the splines.. think that was what happend.. eflite servocrapppppppp....

but man this thing is hewy? it flies as a brick, its a pattern/figure plane at most, surely not a 3D low flying thingy..

It has no choice but to fly that way with that brick of motor up front. it works for that style of flying..pattern.. you can change that with a lighter motor but will not the "best" 3d plane ever. helps take some stress off the landing gear too

I own and fly the E-Flite Carbon-Z Yak 54. I also own and fly the 3DHS Slick 51". I have owned and flown both for many months. The E-Flite Carbon-Z Yak 54 is no 3DHS Slick 51". Two COMPLETELY different planes..

Never meant to say that the Yak matches exactly a 51 slick... not the point I was going for.

Of course every air frame has differences its just people are rating the Yak like it should fly like a flat foam plane, it does not it flies like a balsa 3d plane.

If you can fly 3D stuff with your Slick you can do it with the Yak.

Yes, it flies in the same league as a number of popular 48-51" balsa freestyle planes. It isn't a real light floaty profile plane, it is a relatively scale plane that can fly a lot of pattern, 3D and sport aerobatics. Some of it's competition are a bit more floaty, but don't snap as well, or carry as much momentum into moves, others fly a bit heavier, and can't harrier or hover as well, few are as powerful and fast while still remaining as light and floaty, just a couple of the best. The wing loading is about 16oz per sq ft, almost identical to the 51" Slick(that I also have), the Slick has more control authority, and can feel a bit floatier and more stable, it's due to the design, not the weight, wing area, or wing loading.
